I'm trying this method and when I tried to "piggyback" the wire I really didn't understand how. Am I supposed to push the green/white wire further in it's hole and place my lead wire behind it or should I just touch it there and zip tie it. If I try to put pressure on it, the wire bends etc. I'm not really good with wires and such. Just looking for some guidance. Also, the grounding bold is really hard to get to. Thanks for the write up.
